D:\big\centos>vagrant init centos7
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

D:\big\centos>vagrant up

There was an error while executing `VBoxManage`, a CLI used by Vagrant
for controlling VirtualBox. The command and stderr is shown below.

p24 24、分布式组件-SpringCloud Alibaba-Nacos配置中心-命名空间与配置分组

笔记

• 命名空间
  • 是为了解决配置隔离的问题
  • 隔离开发测试环境
  • 微服务之间配置隔离
• 配置集：所有的配置的集合
• 配置集ID：(DATA ID)类似文件名
• 配置分组
  • 默认所有的配置分组都是default
  • 双十一的时候使用一组,618等等

每个微服务创建自己的命名分组，使用配置分组区分环境,dev,test,pord

内存

xmp

近日发现自己3000mhz的内存条在资源管理器里面显示只有2133mhz

原来是因为xmp没开

参考文献

加内存条

今日发现内存不够用了,便寻思着需要加一个根内存条

按照华硕官方的建议指导手册的建议来插发现，点亮之后发现并没有成功识别第二根内存条(两根内存条参数完全一致)

后来发现有可能是插的不牢固(参考文献)

发现真的没插牢,插内存条的时候听见「柯登」一声响，就插牢了

后来发现没点亮,主板的错误码是CC，主板说明书里面也没有描述这个错误

将两根内存条交换反插，发现能成功点亮

点亮之后，报下面这个信息

图片详情

原来是我开了xmp,F1 重新确认一遍xmp的设置就好了(他会警告你最好cpu要带水冷),F10保存设置并退出，就成功了！

加了内存条超过16gb之后会比较卡顿

关掉虚拟内存

在 $\color{green}{\text{行业内部}}$ 存在着改革的压力，但是 $\color{red}{\text{监管部门}}$ 中反对变革的人坚称，将 $\color{red}{\text{外部人士}}$ 排除在律师事务所之外，可以让律师 $\color{green}{\text{远离}}$ 赚钱的压力，从而遵守职业道德为委托人服务。

Sentence 83

The force of geographic conditions $\color{red}{\text{peculiar}}$ to America, the $\color{red}{\text{interplay}}$ of the varied national groups upon one another, and the $\color{red}{\text{sheer}}$ difficulty of maintaining old-world ways in a raw, new continent caused significant changes.

Sentence 85

Under the plan, for example, the agency said it would not $\color{red}{\text{prosecute}}$ landowner or businesses that unintentionally kill, harm, or disturb the bird, as long as they had signed a range-wide management plan to restore $\color{red}{\text{prairie}}$ chicken habitat.

Sentence 98

Precisely because readers from different historical periods, places and social experiences produce different but overlapping readings of the same words on the page—including for texts that engage with fundamental human concerns—debates about texts can play an important role in social discussion of beliefs and values.

Sentence 99

At Tulane University’s Tear Analysis Laboratory, Dr. Peter Kastl and his colleagues report that they can use tears to detect drug abuse and exposure to medication, to determine whether a contact lens fits properly or why it may be uncomfortable, to study the causes of “dry eye” syndrome and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants.

在杜兰大学的眼泪分析实验室，彼得·卡斯尔博士和他的同事报告称，他们可以用眼泪来检测出滥用毒品及使用药物的情况，确认隐形眼镜戴起来是否合适或者是戴着不舒适的原因，还能用来探究“干眼”综合征产生的原因和眼部手术的效果，也许甚至还能用来测量与环境污染物接触的情况。

Sentence 100

Young people who are still getting started in life were more likely than older adults to prioritize personal fulfillment in their work, to believe they will advance their careers most by regularly changing jobs, to favor communities with more public services and a faster pace of life, to agree that couples should be financially secure before getting married or having children, and to maintain that children are best served by two parents working outside the home, the survey found.

一个正确答案

坑点1:

需要考虑到多项式的值为0的时候,输出为"0"不能有空格"0 "

测试数据中的某个测试点的输出格式错误的测试数据

坑点2:

记得考虑到所有的值都被round了

对应到我的代码中:这个地方也需要round

测试数据中的测试点1

思路

$\xrightarrow{\text{summit}}$读取输入的字符串$\xrightarrow{\text{rectify_data}}$得到的中间数据结构$\xrightarrow{\text{cal_poly}}$得到中间数据结构表示的计算的结果$\xrightarrow{\text{rectify_str}}$得到符合题目要求的正确结果$\xrightarrow{\text{summit}}$输出
